Description

Technical Field

[0001] This utility model relates to the field of nasal mask technology for ventilators, specifically a non-invasive nasal mask for newborns. Background Technology

[0002] A nasal mask is a medical device used for non-invasive ventilation. It delivers pressurized oxygen by covering the nostrils of a newborn, helping to maintain proper ventilation and oxygenation. The design of a nasal mask needs to take into account the anatomical characteristics and comfort needs of newborns.

[0003] Common ventilator nasal masks are generally made of soft silicone material, sealed with a sealing ring, and have connection ports on the surface of the nasal mask for connecting to the tubing of a non-invasive ventilator to deliver gas.

[0004] When the sealing ring comes into contact with a newborn's face, it seals the bottom of the nasal mask. However, when a newborn rolls over, the nasal mask shakes, and the sealing ring separates from the face during this shaking. This makes it difficult for the sealing ring to make close contact with the newborn's face, reducing the sealing effect of the nasal mask. At the same time, because the size of a newborn's face varies, the tightness of contact between the sealing ring and the newborn's face will also vary, causing the sealing ring to exert strong pressure on the newborn's face and causing discomfort. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a non-invasive ventilator nasal mask for newborns. This solves the problem mentioned in the background art where, when a newborn turns over, the nasal mask shakes, causing the sealing ring to separate from the face. This makes it difficult for the sealing ring to make close contact with the newborn's face, reducing the sealing effect of the nasal mask. Furthermore, because newborns have different face sizes, the tightness of contact between the sealing ring and the newborn's face varies, resulting in the sealing ring exerting strong pressure on the newborn's face and causing discomfort.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a nasal mask for a non-invasive ventilator for newborns, comprising:

[0009] A nasal mask housing, wherein a connection port is installed on the front side of the nasal mask housing and a strap is provided on the back side of the nasal mask housing;

[0010] A mounting frame is disposed on the surface of the nose mask shell. The surface of the mounting frame has a mounting cavity. A sealing ring is embedded in the inner cavity of the mounting cavity. A first spring is evenly distributed on the surface of the sealing ring.

[0011] A connecting plate is located on the right side of the first spring. Mounting rods are evenly distributed on the right side of the connecting plate. A control plate is installed on the right side of the mounting rods. Insertion slots are provided at corresponding positions of the mounting frame and the mounting rods. Positioning slots are provided on both sides of the inner wall of the insertion slots.

[0012] Mounting slots are provided on both sides of the surface of the mounting rod. A connecting rod is inserted into the inner cavity of each mounting slot. A positioning head is installed at the outer end of each connecting rod. A second spring is installed on the inner wall of each positioning head.

[0013] Preferably, the second springs are all sleeved on the outer periphery of the connecting rod, and the inner ends of the second springs are all installed on the inner wall surface of the mounting groove. The second springs can compress the positioning head, so that the positioning head can be inserted into the interior of the positioning groove.

[0014] Preferably, the inner cavity of the mounting rod is provided with limiting grooves on both sides, and the limiting grooves are connected to the inner cavity of the mounting groove. The inner end of the connecting rod is provided with a limiting plate, and the limiting plate is located inside the limiting groove. The connecting rod is inserted into the limiting groove, so that the limiting plate can be blocked by the inner wall of the limiting groove, thereby preventing the connecting rod from falling out of the mounting groove.

[0015] Preferably, the nose mask shell is equipped with connecting buckles on both sides, and the straps are equipped with buckles on both sides. The buckles are connected to the connecting buckles at corresponding positions. The bottom of the buckles is provided with a slot, which makes it easy to replace the straps.

[0016] Preferably, the inner wall of the strap is fitted with a flexible pad, and control handles are installed on both the upper and lower parts of the surface of the control panel, so that the position of the control panel can be adjusted by means of the control handles.

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides a non-invasive ventilator nasal mask for newborns, which has the following beneficial effects:

[0019] 1. The nasal mask for the neonatal non-invasive ventilator uses a first spring to compress the sealing ring and a mounting chamber to limit the sealing ring, preventing it from shifting. This ensures that the sealing ring remains in close contact with the neonatal face when the newborn turns over, thanks to the compression of the first spring, thus improving the sealing effect of the nasal mask.

[0020] 2. This neonatal non-invasive ventilator nasal mask allows the installation rod to move by pressing or pulling the control panel, which in turn moves the connecting plate and the first spring. This reduces the pressure exerted by the first spring on the sealing ring. Simultaneously, when the positioning head moves to the positioning groove, it is pressed into the positioning groove by the second spring, thus positioning the installation rod and the first spring. This ensures that the first spring maintains its pressure on the sealing ring, preventing the sealing ring from causing excessive pressure on the newborn's face and improving the comfort of the newborn wearing the nasal mask.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This utility model provides a technical solution: a nasal mask for a non-invasive ventilator for newborns. Please refer to [link / reference]. Figure 1 It includes a nose mask shell 1, with a connection port 2 installed on the front of the nose mask shell 1 and a strap 19 on the back of the nose mask shell 1;

[0034] Please see Figure 3 Mounting frame 3 is set on the surface of the nose mask housing 1, please refer to Figure 4 The surface of the mounting frame 3 has a mounting chamber 4, please refer to [link / reference]. Figure 2 The inner cavity of the mounting chamber 4 is fitted with a sealing ring 5. Please refer to [link / reference]. Figure 5 The surface of the sealing ring 5 is evenly distributed with the first spring 6;

[0035] A connecting plate 7 is located to the right of the first spring 6. Mounting rods 8 are evenly distributed on the right side of the connecting plate 7, and a control plate 9 is mounted to the right of the mounting rods 8. (See also...) Figure 4 Both the mounting frame 3 and the mounting rod 8 have corresponding insertion slots 10. Please refer to [link / reference]. Figure 6 Positioning grooves 11 are provided on both inner walls of the insertion groove 10;

[0036] Please see Figure 6 Mounting grooves 12 are provided on both sides of the surface of mounting rod 8. Connecting rods 13 are inserted into the inner cavity of each mounting groove 12, and positioning heads 14 are installed at the outer ends of each connecting rod 13. Please refer to [link / reference]. Figure 9 The inner wall of the positioning head 14 is equipped with a second spring 15. Please refer to [link / reference]. Figure 7 The positioning heads 14 are evenly distributed on the surface of the mounting rod 8 and are adapted to the position and size of the insertion slot 10.

[0037] The second springs 15 are all sleeved on the outer periphery of the connecting rod 13, and the inner ends of the second springs 15 are all installed on the inner wall surface of the mounting groove 12. The second springs 15 can squeeze the positioning head 14 so that the positioning head 14 can be inserted into the interior of the positioning groove 11.

[0038] The first spring 6 can compress the sealing ring 5, and the installation chamber 4 can limit the sealing ring 5, preventing the sealing ring 5 from shifting. This ensures that when the newborn turns over, the sealing ring 5 can remain in close contact with the newborn's face due to the compression of the first spring 6, thus improving the sealing effect of the nasal mask.

[0039] By pressing or pulling the control plate 9, the mounting rod 8 can be moved, which in turn moves the connecting plate 7, and then moves the first spring 6. This reduces the squeezing force of the first spring 6 on the sealing ring 5. At the same time, when the positioning head 14 moves to the positioning groove 11, it will be squeezed into the positioning groove 11 by the second spring 15, thereby positioning the mounting rod 8 and the first spring 6. This allows the first spring 6 to maintain the squeezing force on the sealing ring 5, preventing the sealing ring 5 from causing strong pressure on the newborn's face and improving the comfort of the newborn wearing the nose mask.

[0040] Please see Figure 8 Limiting grooves 16 are provided on both sides of the inner cavity of the mounting rod 8. These limiting grooves 16 communicate with the inner cavity of the mounting groove 12. Please refer to [link / reference]. Figure 9 Each connecting rod 13 has a limiting plate 17 installed at its inner end. The limiting plate 17 is located inside the limiting groove 16. The connecting rod 13 is inserted into the limiting groove 16, so that the limiting plate 17 can be blocked by the inner wall of the limiting groove 16, thereby preventing the connecting rod 13 from falling out of the mounting groove 12.

[0041] Please see Figure 3 Both sides of the nasal mask outer shell 1 are equipped with connecting buckles 18, please refer to Figure 10 Both sides of the strap 19 are equipped with buckles 20, which are connected to the corresponding connecting buckles 18. The bottom of the buckle 20 has a slot, which makes it easy to replace the strap 19.

[0042] The inner wall of the strap 19 is fitted with a flexible padding layer 21. Please refer to [link / reference]. Figure 3 Control handles 22 are installed on both the upper and lower parts of the surface of the control panel 9, and the position of the control panel 9 can be adjusted by means of the control handles 22.

[0043] The working process of this device is as follows: First, pressing or pulling the control plate 9 moves the mounting rod 8, which in turn moves the connecting plate 7, which in turn moves the first spring 6. This reduces the squeezing force of the first spring 6 on the sealing ring 5. Simultaneously, when the positioning head 14 moves to the positioning groove 11, it is squeezed into the positioning groove 11 by the second spring 15, thereby positioning the mounting rod 8 and the first spring 6. This ensures that the first spring 6 maintains the squeezing force on the sealing ring 5, preventing the sealing ring 5 from being squeezed. The strong pressure on the newborn's face improves the comfort of the newborn wearing the nasal mask. Then, the buckle 20 is snapped into the connecting buckle 18, and the strap 19 is tied to the newborn's head to install the nasal mask. It is connected to the tubing of the non-invasive ventilator through the connecting port 2. Finally, the first spring 6 can compress the sealing ring 5, and the installation chamber 4 can limit the sealing ring 5 to prevent it from shifting. When the newborn turns over, the sealing ring 5 can always be in close contact with the newborn's face through the compression of the first spring 6, which improves the sealing effect of the nasal mask.
